All 15A and 20A, 125V, single-phase receptacles installed in dwelling unit boathouses shall have GFCI protection.

• A. True
• B. False
• C. Only Outdoor Receptacles
• D. Only In Wet Locations

Answer: (A)

Ground-fault protection exists to quickly disconnect power if there’s a ground fault, which greatly reduces the risk of electric shock in wet conditions. A dwelling unit boathouse is considered a wet location because of its exposure to water and moisture. For standard residential receptacles (15A or 20A, 125V, single-phase) installed in such locations, GFCI protection is required. That means each receptacle in the boathouse must have a GFCI device or be on a GFCI-protected circuit. This is why the statement is correct: boathouses fall under the wet-location requirement, so GFCI protection is mandated.
